Buna-N 90 Durometer O-Ring .176 ID for Sealing & Gaskets

Our Buna-N Nitrile O-Ring 90 Durometer Size -008 (0.176″ ID) delivers reliable sealing performance in demanding environments where oil resistance and durability are critical. Engineered with premium nitrile rubber, this industrial-grade seal excels in automotive, machinery, and hydraulic systems exposed to petroleum-based fluids, fuels, and extreme temperatures. Its 90 Shore A hardness ensures robust compression resistance under high-pressure conditions, maintaining structural integrity even in harsh operating scenarios.

Perfect for applications requiring consistent sealing in pumps, valves, or engine components, this o-ring combines chemical resilience with precise dimensional stability—measuring 0.176 inches inner diameter (ID) and conforming to standard -008 sizing specifications. Unlike softer alternatives, its firm durometer rating prevents deformation over time while resisting ozone exposure and abrasion for extended service life.

Whether you’re assembling industrial equipment or repairing automotive parts, this o-ring offers a cost-effective solution for preventing leaks in oil-filled systems. Its compatibility with common lubricants and fuels makes it ideal for mechanics, engineers, and manufacturers seeking a dependable seal that withstands everyday wear without compromising safety or efficiency.

Crafted to meet industry standards for precision and reliability, this nitrile rubber o-ring balances performance with affordability—ensuring seamless integration into your critical applications without compromising on quality or longevity.
